I love my Dell Studio 1555, it's a great computer!
I got this computer as a replacement of my old Inspiron (running Windows Vista) and as a laptop for college. Running Windows 7, this thing is a beast. It does everything I need it to do for school and it runs perfectly. I have had a few issues with my computer. The right click button on the touchpad broke, but with my warranty Dell came and fixed it. Also, the plastic on the frame broke near the hinge but it was also covered under warranty. I would definitely suggest getting a warranty for this computer, it covers really well and Dell is super easy to work with to get things fixed.
